BISCUIT-ICING MACHINE.

Specification of Letters Patent.

Patented Sept. 14,1915.

. To all whom it concern:

Be it known that we,- THOMAS VIoARs, J OHN VICARS, and EDWARD LYNTON VICARS, subjects of'the King of Great Britain, residing at Earlestown, in the, county of Lancaster, England, have invented new and useful Improvements in Biscuit-Icing Machines, of which the following is a specifica tion. a

This invention relates to that kind of machine in which an endless traveling band is used for conveying the icing. Hitherto the speed of these machines has been comparatively slow and the capabilities of varying to our improvements. Fig. 3 is a detail view of the icing gage.

a is an endless traveling band dipping into the icing trough 'b and passing under a roller 0 therein and carried outside around rollers (Z, 6 so arranged that the icing to be deposited is on the lower side of the band when passing around a roller f below the bottom of the trough b; any icing adhering to the other side belng removed by a scraper g as usual, and a gage h is used to regulate the thickness of icing on the band. This band may be driven by one of the rollers d through a pulley i which may be operated from coned pulleys and belts, as shown in dotted. lines, ratchet and pawl gearing, or other convenient variable speed devices so that the speed may be varied to any desired extent.

The icing trough b issupported on the framework j by lugs and plus is so that it may readily be detached for cleaning and refilling. The roller 0 is supported in position by brackets Z from the framework 3' and the roller 6 is preferably carried on arms m pivoted at n and secured by screws 0 so that the tension of the band may be regulated. Underneath the bottom roller 7 we arrange another endless band 39 traveling around rollers q, 1", which band carries the biscuits to be iced under the icing band a and thls carrier band p may be driven by pulleys from coned pulleys and belts, as shown 1n dotted lines, ratchet and pawl gearlng, or other convenient variable speed devices, so as to vary the speed of the band 79 to any desired extent. This means of varylng the speeds of the icing band and the carrier band allows of regulation of the icing to a very large degree If the carrier band p is driven at a slow speed and the icing band a at a quick speed in the direction shown by the arrows and the gage h is arranged for a thick layer of icing the biscuits will receive a very thick coating of icing, if the bandp is driven fast and the band a slow, and the'gage k arranged for a thin layer the biscuits will receive a very thin coating of icing.

The carrier band may be provided with recesses or with projections t to prevent displacement of the biscuits by contact with the icing. The carrier band or a part of it immediately below the said bottom roller f is arranged to be raised or lowered by a table u'adjustable byscrews 'v, or by a roller, or other convenient device, according to the thickness of the biscuits and of the icing required on them; or instead of moving the carrier band the icing band a or part of it might be raised or lowered by moving the roller f, which for this purpose may be journaled in bearings w vertically movable in guides w and adjustable by screws 3 WVhen several lines of biscuits are arranged on the width of the carrier band the icing gage may be so arranged, as shown at a Fig. 3, that the icing is scraped off those parts of the icing band corresponding to the intervals between the lines of biscuits.

We claim,

1 In a biscuit icing machine the combination of an endless traveling icing band passing around a roller and devices for conveying biscuits in an opposite direction underneath that part of the band passing around the roller, the roller being arranged so that the icing band does not parallel to the biscuits, substantially as set forth.

2. In a biscuit icing machine the combination of an endless traveling icing band pass-' ing around a roller and an endless traveling biscuit carrier band passing in an opposite direction underneath the icing band around bination of an endless traveling icing band passing around a roller, devices for conveying biscuits in an opposite direction underneath that part of the band passing around the roller, whereby the portions of the band branching from the biscuit conveying devices form a contacting portion traversing the conveying devices along a single line across the latter, and devices for varying the distance between the icing band and the conveying devices, substantially-as set forth.

4. In a biscuit icing machine the combination of-a variable speed endless traveling icing band passing around a roller, said band branching upwardly from said roller, said band and biscuit conveying devices being adjustable toward and away from each other at the point of application of the icing during the operation of the machine, and

variable speed devices for conveying biscuits be accomplished and means operative bein an opposite direction underneath that part of the band passing around the roller,

substantially as set forth.

5. In a biscuit icing machine, a frame, an:

icing trough supported thereby, a plurality of rollers journaled in said frame above and below said trough, an endless band 'traveling around said rollers, an additional roller journaled in said trough and beneath which said band passes, rollers journaled in the frame beneath the lower portion of said end less'band, a second endless band operating around the last mentioned rollers and having the lower roller around which the aforesaid band operates disposed intermediately and transversely of its upper lap whereby icing trough supported thereby, a plurality of rollers ournaled in said frame above and below said trough, an endless band traveling around said rollers, an additional roller journaled in said trough and beneath which said band asses, means for moving said band at variable speeds, means for scraping the icing ing the icing on the other side thereof, the

from one side thereof while leavlower portion of the band passing around a single roller, means to adjust said latter roller vertically, a pair of rollers journaled in \the frame nbeneath the last 'mentioned roller, an endless biscuit conveying band passing around said last mentioned rollers,

means for driving said last mentioned band at variable speeds, and in opposite direc-- tion to the direction or movement of the first mentioned band whereby variation in the quantity of icing applied to the biscuits may neath the upper lap of the lower'band to adjust the same vertically in cooperation with THOMAS VICARS. JOHN VIGARS. EDWARD LYNTON VICARS.
